Warframe

Warframe is Digital Extremes' free-to-play co-op action game about the Tenno warriors, their Warframes and an arsenal of weapons. The game is vast: dozens of Warframes, hundreds of weapons, mods, quests and open worlds, and gathering everything a strong build needs takes a lot of time.

Much of Warframe's economy runs on trading between players, so on the marketplace people buy Platinum, store bundles and Prime Access, accounts with a high Mastery Rank, and Riven mods with random stats.

Before buying, confirm the platform: PC, consoles and the mobile version differ, and meeting a player on another platform for a trade may not be possible. For anything delivered by trade, keep the game's trading rules in mind: two-factor protection must be enabled on the account, the number of trades per day depends on Mastery Rank, and the trade tax is paid in credits. Bundles come as codes, gifts sent to your in-game name or purchases made through an account login, and some are limited to one per account. The developer's rules do not allow account transfers, which is worth bearing in mind.

Purchases go through a deal on the marketplace: payment is held by the site until you have checked the goods and confirmed receipt. If there is a problem, open a dispute before confirming and a moderator will review the chat and screenshots. An optional guarantee package can be added to an account purchase.

Tip: enable two-factor protection before you pay, because without it the trade with the seller simply will not happen.
